NIECHANISIVI FOR CUTTING OUT HEEL-L-IFTS.

SPECIFICATION forming part of Letters Patent No. 236,162, dated January4, 1881.

Application filed July 24,1880. (No model.)

To all whomit may concer/n.:

Be it known that I, GEORGE JAMES, ot Boston, county of SuftollgState ot'Massachusetts, have invented an Improvement in Mechanism for Cutting outHeel-Lifts, of which the following description, in connection with theaccompanying drawings, is a speciiication.

This invention relates to mechanism for cutting out heel-lifts, and vhasfor its object to furnish an apparatus to cut out heel-lifts inaccordance with the plan describedin my United States Patent No.219,553, dated September 16, 1879, to which reference may be had,y therounded ends of the heel-lifts of one section being made to fall inbetween the rounded ends of the other series of heel-lifts, such systemof cutting reducing the waste leather to the minimum.

Figure 1 is a top view of my improved apparatus for cutting outheel-lifts, the figure showing the vertically-movable bed or support,its attached gages, and the edges of the cutting-dies. 2 is a left-handend view, and Fig. 3 a section on the line x x, Fig. 1.

The base a of the machine has suitable openings, b, coinciding with eachheel-lift cuttingdie c c. Standards 2, properly threaded, receiveset-screws 3, by which to adj ust and hold the dies firmly in position.

The support or bed d has at its under side legs or rods, d', which areextended through springs e and openings in the base a. The springs restupon and sustain the support or bed d in such manner as to permit it todescend under pressure applied at its upper side and compel it to risequickly when relieved of such pressure. l

Attached to the support d at one edge is the edgegage f, against whichone of the longer edges of the strip to be cut into heellifts is keptpressed to guide or direct the strip forward in a straight line. I

Near the farthest side of the die or cutter c there is secured to thesupportd a registering or heel-lift gage, g, shown plainly in Fig. 3, itbeing, as therein shown, provided with a shank, g', guided in a bracket,g2, and surrounded by a spiral spring, g3, to permit the gage to adaptitself to the size of the die or cutter being used,

the spring being strong enough to keep the gage pressed against thecutter or die.

Near the die lor cutter c I have placed two gages, 7L h', eachconstructed as the gage g.

In Fig. l the dotted lines of regular length represent the outline of astrip ot' sole-leather from which two or more lifts have been cut, andthe said strip is supposed to be in position to be again cut as thesupport and table again descend. In the ligure, the curved edges ot' thesole-leather next Where the heel-lifts were previously cut out restagainst the gages g It h', which correctly position the leather over thedies or cutters c o', so as to necessitate the least possible quantityof leather, and so placed, a wooden or other suitable block, presser,stamp, or hammer, operated by power or hand, is caused to descend orfall and strike the upper side of the leather, when it and the supportcl descend far enough to cause the dies or cutters to cut through theleather, the heel-lifts passing down through the dies or cutters andbeing discharged from the openings b. As soon as the leather is relievedfrom pressure the support or table d rises under the action of thesprings, lifting the leather from the dies, when the leather may beagain moved forward against the lift or registering gages g h h'.

I am not aware, prior to this my invention, that a gage has ever beenused near a xed die or cutter so as to exactly position the leather withrelation to the die before cutting out the lift. lu my apparatus I amenabled to cut out two lifts simultaneously, and by placing the dieswith relation to each other as shown in Fig. l, I am enabled to cut outthelifts with the minimum Waste ot' stock.

The gages g It 7L are lnade to come close into Yline with the edge ofthe cutters when the bed d is elevated. The metal forming the cutters isbeveled, and as the bed'is depressed the said gages strike the beveledouter portions of the cutter and recede.

I claiml. In an apparatus -for cutting out heellifts, two stationarydies, located with relation to each other as described, combined with amovable supporting bed or table and registering or lift gages locatedabout the edges of In testimony whereof' I have signed my the dies, toact upon and position the edges ot' name to this specification in thepresence of 1o the leather left by cutting out other heel-lifts twosubscribing' Witnesses.
